The Mobile Internet
I just changed my mobile provider, to get a phone I could actually use at home.
My old provider (Orange) provides casual GPRS access for £3/MB. By 'casual' I mean I don't want to hand over money every month for something I probably won't use. But if I am out and about, I run Opera on my Palm T3, and that's a much better internet experience than the matchbox sized screen on my Moto V3.
So now I'm on T-Mobile; their casual access is £1 per day for 'fair use' access, and the chap in Carphone Warehouse was sure that I could access the internet from my Palm on this. But no; the £1-per-day tariff only allows you to use the browser on the phone. And so does the first 'bundle', at £7.50 per month. You have to be willing to cough £12.50 and £22.50 per month if you want to connect a handheld or laptop to GPRS.
Now here's the real rant. Their website doesn't make this limitation clear, so any ex-Orange customer coming to T-Mobile could make the same mistake. Actually, none of the operators sites, say anything clearly about the 'walled garden' experience, or how much you need to pay to get the mobile internet off your phone and onto a device that you can actually read.
The moral of this rant, fellow vultures, is be careful to understand the Ts&Cs for yourself before you choose.
